<p>Emaheevul07, I think painting over a primer with a primer and paint in one will work okay but you are paying more money for a paint that has the primer in it already, so it’s adding to your total cost without really giving you a better paint job. This is assuming you would be using a premium paint that does not have a primer already in the paint. A good example of this would be Benjamin Moore Aura versus Regal Select. Aura has a primer in it and Regal Select does not, making Regal Select a little less expensive than Aura.</p>
